Station log
From Memory Alpha, the free Star Trek reference
A station log is a type of log used on board space stations to record the events which happened on them. It is primarily used by the commanding officer if holding the rank of commander or lower.
Commander Benjamin Sisko recorded in the station log aboard Deep Space 9 until he was promoted to captain. (DS9: "The Adversary")
Lieutenant Junior Grade Aquiel Uhnari made entries in the station log of Relay Station 47 in 2369. (TNG: "Aquiel")
